The apparatus ormachine'iormingthe sub- 110 line 21e-2a 70 to Fig. showing the 9o ject matter of this applicationA is a continuation in part of application bearing Serial Number 661,099 led March 16, 1933 and is designed for the production of the links or coupling members of separable fasteners and the machine elements diagrammatically illustrated and the method described and claimed in the above identified application.

It will be understood that while dies are fashioned to produce links or coupling elements of the class under consideration, the contour of the dies employed may be varied to produce other types or kinds of elements, and in like manner, the parts of the machine revised or modified to adaptthe same to such other uses or adjustments made in the machine to compensate for other uses or different sizes of elements to be formed by the'dies.

To illustrate one use of the invention, the accompanying drawings disclose a machine and parts thereof consisting of a main drive or power shaft 20 having at one end a pulley 20a by means of which the shaft is driven from a suitable source of power, not shown as it does not form any distinct part of the invention.-

The shaft 20 is mounted in bearings of two side frame members 21, 21a, arranged upon a suitable base or support 2lb, note Fig. 1, and these frames are joined'bya front frame plate 22. Arranged within the frame is a substantially box-shaped casing 24 forming 'a support for the container or pot 25 for the molten metal or other casting material.

The casing 24 has grooves 24a on the side walls thereof and rollers 26 and 27 are supported in connection with each side' frame and operate in the grooves 24a to guide the casing 24 in its forward and backward movement in the frame. 'I'he rollers 26 at the front of the frame and casing are rotatably supported on hollow pins 26a eccentrically disposed within bushings 26h so as to adjust the casing 24 vertically in the frame to properly vposition the nozzle 28 of the pot 25 with respect to dies 29 and 30 to insure proper alinement therewith. Lock nuts 26e are employed to retain the rollers in their desired position of adjustment, and it will be seen that cool water may be circulated into the tubular pins through pipes 26d from the supply tube 26e and discharged from the bore of 'the pins 26a fromthe tubes 26j, note the left side of Fig. 1 of the drawings.

'I'he purpose of cooling the rollers is to prevent the flow of heat into the frame members, especially at the forward part of the machine, and it will be understood that the rollers 27 may be cooled in a similar manner if desired. However, it is not essential that the rollers 27 be adjustably Asupported, the adjustment of the front rollers being sufficient to provide the proper alinement referred to. "I'he casing 24 includes a donwardly directed, fork-shaped extension 24h on which is supported a block 24o having trunnions- 24d extending laterally therefrom to engage the recesses in the separate members of the extension 24h.

Slidably mounted in the block 24e is a rod 23 pivoted to the front plate as indicated at 23a and arranged on this rod upwardly of the block is a spring 23h, the tension of which is controlled by a winged nut 23e in threaded engagement with the rod. The purpose of this conthe casting operation. Cams 31 are employed for operating the dies 29 and 30 as later described.

The pot 25 is mounted in and insulated from the casing 24 and includes therewithin a vertical cylinder 25a. opening through the ltop of the pot and downwardly into a goose-neck passage 25h, the upper and outer end of which opens into the port 28a of the nozzle 28, the latter being detachable with respect to the pot 25. It will appear that the nozzle opens into a large recess formed in the top forward end ofthe casing, and mounted on the protruding end of the nozzle is an electric heating unit 28h, by means of which the nozzle may be kept at the required temperature to maintain the casting material in a flowing state to facilitate the formation of proper castings. The circuit wires to the heating unit 28b are diagrammatically illustrated at 28e and 28d in Fig. 2 of the drawings.

A plurality of heating plates 32 are disposed on the outer surface of the pot 25 within the casing 24, preferably on the bottom and sides of said pot, in order to maintain the casting or molding material within the pot at the proper temperature at all times, and the circuit wires to these heating plates are diagrammatically `illustrated at 32a, 32h, 32o, 32d and 32e. The electric circuit in itself forms no direct part of the invention and for this reason is only diafgrammatically illustrated. In practice, the circuit wires will enter the casing 24 through a suitable fitting or coupling 32j mounted on a cover plate 32g controlling admission to a. large chamber 33 at the back of the casing, in which is arranged a series of terminals or binding posts 33a, with which the circuit wires 32a to 32e are coupled. At the lower end of the cylinder 25a is an admission port 25e whereby the casing -or molding material from the pot 25 may enter the lower end of the cylinder as well as the gooseneck passage 25h.

Mounted in the cylinder 25a is a piston or plunger 34'at the upper end of which are two collars 34a between which are disposed the forked ends 35a of a rocker arm 35. The arm 35 includes a part 35h pivoted to an extension on the frame 21a as seen at 35e, the arm 35 having a yoke-shaped portion 35d pivoted to the part 35hby a pin 35e, note Fig. 1 of the drawings, the purpose of which is to permit swinging movement of the arm 35 consistent with and during the forward and backward movement of the casing 24 and the nozzle 28 movable therewith.

The free end of the part 35h of the arm is yoke-shaped in form and rounded as seen at 35f and seat's between collars 36 on a rod or plunger 36a. The plunger 36a hasat its lower end a follower 36h slidably mounted in guideways 37 on the frame 21a, and on the follower is a roller 36e operating upon a cam 38 on the shaft 20. Disposed on the plunger is a collar 36d upon which a spring 36e seats, said spring also seating on the lower and free collar 36 at the upper end of the plunger, so that as the plunger is moved upwardly by the cam38, the rocker arm 35 is actuated through the spring 36e to depress the plunger 34, it being understood that the spring will be of suiiicient tension to give the requiredl pressure to perform the function desired and yet will prevent any breakage to the machine should the plunger stick or be jammed or rendered inoperative by reason of any improper condition of the casting material. It -wiu be undrstood that the lower end of the plunger 34 is normally 150 disposed abovethe port 25e as is indicated in Fig. 2.

In the upward movement imparted to'the rod 36a, a crosshead 39 at the upper end thereof is raised and this crosshead has at its ends rods 39a extending down through guides 39h on the frame 21a. The lower ends of the rods have adjustably supported 'collars 39e operating upon springs v39d so that said springs are placed under compression in the upward movement of the rods 39a. The springs 39d serve to return the plunger rod 36a as well as the piston or plunger 34 to raised position and also to maintain the roller 36o in constant engagement with the cam 38.

On the part 3517 of the rocker arm is an adjustable stop screw 40 engaging a part of the frame 21a. to limit the downward movement of the plunger rod 36a as well as the upward movement of the piston 34. Thecircuit wires to the e heating elements em'ployed are connected with a switch or control board 41 diagrammatically illustrated in Fig. 2 of the drawings, and the ground side of the circuit from the wire 32e extends to a pyrometer indicated at 41a. 4 A series of automatic switches 41h are employed in the circuit wires to control the temperature of the material in the pot 25, a suitable resistance 42 being employed in the circuit wires 28o, 28d controlling the'nozzle heating unit 28b. At 41e and 41d 'are shown the circuit wires from a source of vsupply entering the board which is diagrammatically illustrated.

The dies 29 and 30 are slidably mounted in the front plate 22 of the frame and the inner adja- :cent surfaces of these dies have registering mold chambers 29a, 30a of such contour as to form the links 43 of a separable fastener as is illustrated in Figs. 3 to 15 inclusive. The outer end of the nozzle 28 at all times seats on the surface of the dies 29 and 30, note Figs. 8 and 10 and is held in engagement therewith by the spring 23h. The dies are provided at their outer sides with grooves 29h, 305 to receive the corded edge of the tape 44 and also with recesses 29e and 39e to receive the mounting tape,- strand or member 44 beyond said corded edge.

Below the mold chambers 29a., 30a, the dies have surfaces 29h, 30d against which a previously formed link or element 43 is adapted to rest in the operation of spacing the links 43 on \the mounting member 44 and also in removing the core 45 from the formed link, the core fitting between the dies 29 and 30 with its inner reduced end 45a. disposed within the mold chambers of -die dies so as to form a recess or aperture 43a at one side face of a coupling link 43 to receive the body or projecting member 43h on the opposite side face of an opposed link, the latter. being formed by the. contour of the mold chambers Vof the dies. The dies also in`- clude recesses 29e, 30e for receiving the core die part later described and between adjacent surfaces thereof is formed a port 30f by means of which casting material may be. introduced into the mold chambers 29a and 30a. The mold chambers of both dies arevalso recessed as indicated at 29) to form the projecting member 43h on the ring'.

The dies 29 and 30 .in the construction shown, are 'in the form of relatively long strips of -metal having water circulating chambers46, 46a. 're'- spe'ctively' so that the dies ,may be 'maintained ,in a coolv state or 'at the` proper temperature in the kcasting ,operationsand wateris introduced into the chambers 46, 46a through intake tubes or pipes 4Gb at the outer ends of said dies and is discharged through exhaust tubes 46c at the adjacent ends of said dies, note Fig. 3 of the drawings.-l Each die 29 and 30 has on its upper surface an upwardly projecting lug 47, 47a disposed angularly to a plane transversing the Alongitudinal plane or path of movement of the dies, note the right end of Fig. 3 of the drawings, where the lug 47 is shown in section.

These lugs operate in corresponding annular channels 475, 47e respectively in short bars 48 adjustably supported with respect to the forward eds of long bars 48a by bolts or screws 48h secured to the bars 48 and passing through elongated apertures 48e in-the ylong bars 48a, note Fig. 4. This adjustment is to compensate for accurate abutment as between the dies, and it will be understood that the long arms 48a will have wider grooves to compensate for this adjustment as clearly seen at the right of Fig. 3. The bars 48a are disposed at opposite sides of the machine adjacent the frames 21 and 21a and movable forwardly and backwardly in suitable guides in said frames. The inner ends of the bars 48a extend in rods 48d upon which are i mounted coil springs 49 seating upon the frame.

in constant engagement with the cams 31, the

cams operating to separate the dies 29 and 30, whereas the springs 49 serve to hold the dies firmly in engagement with each other, sufficient clearance being allowed between the rocker arms 50 and slide bars 48 to permit this operation.

The core 45 is in the form of a pin or rod, the upper `end of which is offset as at 45h to engage an aperture in a core supporting plunger 45o, the latter having at its upper end a cross pin 45d entering a notch or slot in the protruding arm 51 of a block 51a clamped to a rocker shaft 52 mounted in the upper end of the frames 21, 21a. The shaft 5 2 projects outwardly beyond the frame 21 and rotatably mounted thereon is a r'ocker arm 53 having a yoke-shaped crosshead 53a at its outer end and a long arm provided withian elongated aperture 53h, at its other end. Keyed tothe shaft 52 is a block 54, the head 54a of which is disposed between the yoke-shaped crosshead 53a and has an arcshaped aperture 54h through which is passed a lock bolt 54e, the latter being mounted in the crosshead 53a.

On thearrns of the crosshead are adjustment screws 53e cooperating with the head 54a 'to control adjustment of the rocker arm 53 with respect to the shaft to regulate or` adjust the vertical position of the corewith respect to the arm having .the elongated aperture 5317. Thel arm- 55 has asquare end 555 operating vupon a crosshead 56 on the-shaftl 20, permitting sliding vmovement of the squared end 5517 with respect to the crossheadv and'shaft'20. UDn the end 55h of the arm 55 isa roller 55o which operates in the groove of a cam 5'7 secured tothe shaftY 20fand this cam serves to operatethe .150

score to feed the formed link and to space said Itape.

link and its mounting tape in the operation of the machine.

' The core supporting plunger 45e is mounted between two similar guide plates 58 .having laterally extending flanges 58a including key pins 58h entering the front plate 22 of the frame, note Fig. 7. The plates 58 are clamped together by screws or other devices, and between these plates is an adjustable spacing and backing plate 59, the inner end of which guides and spaces the outer edge of the mounting strip or tape 44 which is also guided by the. plates 58. The plate 59 has elongated apertures 59a, note Fig. 2, through which the clamping screws or bolts pass, and these apertures permit inward and outward adjustment of the plate 59 to compensate for mounting strips or tapes of different widths. The plates 58, 59 form a guide unit which in its assemblage is detachable with respect to the frame; and when detached, the plunger 45e may be removed therefrom. This unit is held in place by two clips 60 adjustably clamped to the plate 22 by milled screws 60a, note Fig. 7. The strip or tape 44 from a spool or drum 44a diagrammatically illustrated in Fig. l passes over an idler 61 supported on a bracket 61a on the frame 21a of the machine, the tape passing over a plate 61h on said bracket, and a flat spring 61e engages the tape as it passes over said plate to apply the required spring tension or friction to the tape to permit proper feeding thereof as it is drawn into and through the machine by the feed heretofore mentioned. From the plate 61h, the tape 4passes over another idler 62 and from this idler down through the guide unit consisting of the plates 58, 59 and the tape with the links thereon after being fed from the dies 29 and 30 extends downwardly between a feed disk 63 having a projecting roughened surface 63a and a roller 64 movable toward and from the disk 63, the purpose of which feed is to intermittently cause a fairly long length of the strip to be fed through the machine in/v order to space the groups of coupling elements on the'strip to form independent Stringer sections. For example, in Fig. 15 of the drawings, it will be seen' that the group of coupling elements 43 at the top of said figure is`spaced apart from the group of elements indicated at the bottom of said figure by a long portion ofthe tape, upon which end coupling elements are secured. In the manufacture of the stringers, the said blank portion is severed centrally between the respective groupsv of coupling elements to provide ends facilitating attachment to various articles of manufacture in connection with which the stringers are used.

The disk 63` is mounted ona shaft'65 supported in -a suitable bearing in the front plate 22, the shaft having at its inner end a beveled gear 65a meshing with a vcorresponding gear 65h on the shaft 20, and by this means, the disk 63 is'rotated.` The inner surface of the disk 63 has a surface vcam groove 63h and inwardly thereof another small cam 63c. The roller 64 is mounted on a bar 64a slidably mounted in the frame 22, ,and at the inner end of the bar is a roller 64b engaging the cam 63c to permit inward movement of the roller 64 into engagement with the surface 63a to cause the sudden feed of the The roller 64b is held in engagement with the cam 63c by a spring 64e and at the outer end of the bar 64a. is a stop 64d adapted to be engaged by a pawl 66 pivoted as seen at 66a to 'shaft 20 in Figs. 1 and 5.

control the inward movement of the bar 64a. The pawl 66 is moved into inoperative position by an offset or trip member 67 on one or more of the links of a chain 67a passing around a sprocket 68 on a shaft 69 mounted in a projecting bracket portion 22a on the shaft plate 22. To theA inner end of this shaft is secured a worm gear '70 engaging a worm '70a at the end of the The sprocket is driven through a spring clutch 69a at the outer end of fthe shaft 69 as indicated in Fig. 5 ,of the drawings, so as to obviate any possible breakage shouldobstructions occur or improper timing be occasioned, especially 'in the initial setting up of the machine after changes in the size of dies or other elements have been made. It will be understood that the timing arrangement of the quick feed of the tape hele referred to is controlled and regulated to be performed when the dies are in separated position immediately after the core 45 has been removed from a formed link and prior to the movement of the dies into closed position. It will appear that the hook end 665 of the pawl 66 is held in operative engagement with the stop 64a by a spring 66e as .clearly indicated in Fig. 1 of the drawings.

On the face of the front plate 22 are angularly disposed guide members 22h formed into channels by retaining strips 71 which guide a trimming plunger 72 in the frame, the latter having a knife or blade 73 adjustably supported thereon by means of an adjustment screw 72a in order to provide very definite adjustment of the cutting edge 73a of the blade 73 with respect to each link and the die, note in this y respect, Fig. 9 of the drawings. The knife or blade 73 is employed to trim off thegate 43e of the cast link as is represented in said figure. vWhen adjustment is made, the blade is clamped to the plunger 72 by screws '13b passing through elongated apertures in said blade.

At the lower'end of the plunger 72. is a roller 72b which operates in the surface cam 635 of the disk 63, and it will be understood that after each link is formed and moved into a position below the die or in engagement with the surface 29d thereof, the gate 43o is trimmed from said formed link in the operation of forming the next adjacent link as is indicated in Fig. 9 of the drawings. 'Ihe dies 29 and 30 are slidably supported between foutwardly extending parallel flanges 74 at opposite sides of the front plate 22 and are retained between said flanges by removable plates 75. In the bottom anges are adjustment screws 76 adjacent the ends of said flanges, operating upon an alinement plate '16a in order to maintain the dies 29 and 30 in proper vertical'alinement in thev machine with respect to the nozzle 2,8, the plate '75 permitting quick attachment and detachment of the dies a's willA be apparent, this construction being seen in Figs. 1,'2, 4 and 5 of the drawings.

'I'he operation of the machine will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following statement. VStarting from a point in thecycle of operation where the dies are in closed position as indicated in Fig. 8 of the drawings with the mounting strip or tape 44 disposed therebetween and with the nozzle 28 abutting the dies and core 45 between said dies, the. next step in the operation will consist in forcing or injecting under pressure the molten metalor other material into the mold 150 chamber formed between the die parts, which result is accomplished by the descending operation of the piston or plunger 34 in the cylinder 25a through the action of the rocker arm 35,

`spring 36e operated by roller 36e engaging cam 38. At the same time, the trimming knife or blade 73 is moved into position to trim off the gate 43e of a previously cast link 43, the knife being actuated by the cam groove 63band the roller 72b operating therein.

The next function of the machine consists in separating the dies as is indicated in Fig. 10 of the drawings. This operation is performed by the inward movement of the slide bars 48, 48a against the tension of the springs 49, made possible by the rocker arms 50 actuated through the cams 31, it being noted in Figs. 8 to 12 inclusive that the nozzle 28 is held in engagement with the dies at all times by means of the spring 23h shown in Fig. 2 of the drawings.

When the dies 29 and 30 have been opened,- the next step in the operation is to feed the last formed link 43 including the tape to'which it is attached downwardly, itbeing understood that the. cast link remains upon and is supported by the core v45. The operation is performed by the cam 57 which actuates the arm 55 through the roller 55e, the arm 55 operatingI the rocker arm 53 to rotate the shaft 52, which in turn operates the arm 51 of the block 51a and moves the core downwardly through the core plunger 45e. This downward feed of the plunger and the cast link thereon brings the parts into the positionshown in Fig. 12 of the drawings, with the upper surface of the `cast in alinement with the lower surfaces 29d, 30d of the dies.

The cams 31 now function to permit a partial closing of the dies 29, 30 into the positions indicated in Figs. 13 and 14 of the drawings so that the surfaces 29d and 30d may be brought above the links to prevent upward movement thereof, after which the core is moved upwardly by means of the action of the cam 57 and the asso# ciated parts above referred to, thus leaving the said cast link supported temporarily between the partially closed dies. After the core has returned to its raised position similar to that indicated in Figs. 9 and 11, the dies are again opened and quickly closed, returning the parts to the positionl shown in Fig. 8. `In the last above stated opening movementy of the dies 29 and 30 from the position indicated in Figs.v 13 and 14 to a position susbtantially similar to that indicated in Fig. l0, the quick feeding of the tape by means of the feed disk 63 and roller 64 may be performed, it being understood, however, that this operation is only after casting a,.pre determined number of links on the tape, which would designate the desired grouping of' links or govern the 'length of the stringer desired. In this connection it will be understood that the length of these groups of coupling elements or stringers may be a matter of an inch or morei to the conventional lengths ofA six and nine inches or to a length of many yards. depending entirely upon the requirements..

In the above operation it willfbe understood that after the metal has been injected into the dies, the metal in the end of the nozzle 28 is drawn back into the nozzle or goose-neck 25h thereof by the upward movement of the piston or plunger 34, it being also understood that the heating unit 28h on the nozzle serves to maintain the nozzle'heated to prevent'any possible chilling of the casting material in the nozzle during the operations of feeding a formed casting and repositioning the mountingt tape and dies for the next casting to be formed.

The cycle of operation of the machine above referred to is completed upon a revolution of` the shaft 20 and is repeated at each revolution of said shaft, as will be apparent.`

The pyrometer includes .circuit wires '77 and 77a which extend to a temperature control tube or device 78 which includes a portion t,78a extending into the molten metal or other casting material to automatically control and regulate they temperature and permit the functioning of the automatic switches 41h. The pins 26a are provided at their inner ends with enlarged heads -having rounded surfaces 79, note the right hand of Fig. 1 of the drawings,` and these pins are adjustable in bushings A2Gb so as to aline the casing 24 laterally in the frame to properly position the nozzle 28 with respect to the dies, and this adjustment plus the eccentric mounting of the pins provides. substantially a universal adjustifient of the casing for the purpose stated and the nuts 80 retain the pins in different positions of adjustment.

As heretofore stated, different types of casting or molding materials may be used such as various kinds and classes of metal which are suitable for the purpose intended and which will depend to a large degee upon the particular type and character of the mounting strip employed well as thermoplastics capable of being molded or cast in a machine of the class under consideration in accordance with the later teachings in this art. A y

As previously stated, it will be understood that the invention is not limited to the formation of coupling links or elements as other bodies or members of this kind maybe formed in the production of various kinds and classes of merchandise, and still further, in dealing with the production of coupling elements forming the links of separable fasteners.A It will also be apparent that the invention is not limited to the shape, contour or sizeof the coupling elements or links formed, it being possible to shape and form the dies in any desired manner within the working functions of this machine, the only requirements being that the core or mold chambers of the die parts be such as to pull away from the cast or molded product.

It will also be understood that the invention disclosed is not necessarily limited to the particular combination of machine elements herein disclosed for performing the several functions and operations of the machine,l and y various .other changes in and modifications of the construction herein shown and described may be made within the scope of the appended claims withoutdeparting from the spirit of the invention or sacrificing its advantags.
